Disclosed herein is an improved high-efficiency solar-charging electric window candle comprising a base adapted to sit securely upon a window sill. The base includes a footer formed with a battery compartment accessible through a bottom hatch, and a riser protruding upwardly from the footer with upwardly inclined side surfaces. The riser also has a compartment for enclosing a circuit board, and a vertically-oriented collar. A rechargeable battery is mounted in the footer of said base, and a hollow cylindrical candle body is inserted in the collar of the base riser, and a bulb assembly comprising a white LED is mounted atop the candle body. A circuit board is enclosed in the riser and includes two circuits: a current pump for supplying a pulsed current, and a photosensing circuit for sensing ambient light levels. The charge pump circuit reduces current requirements of the white LED, and the photosensing circuit automatically detects ambient light levels and illuminates the white LED while disconnecting the rechargeable battery, or vice versa, depending on whether there is sufficient ambient light.

The invention relates to a magnetic levitation vehicle (11) and to a method for lifting said magnetic levitation vehicle (11) and to lowering said magnetic levitation vehicle onto a roadway. According to the invention, the carrier magnetic units (38) of the magnetic levitation vehicle (11) are not all activated or deactivated at the same time but at different times in order to keep the current energy requirement from an external energy supply or main power supply to a minimum.

A bidirectional crosspoint switch interface employs a pair of backward-connected transimpedance amplifiers of the type disclosed in the L. Enriquez U.S. Pat. No. 6,411,163, and associated scaling current mirrors that drive nodes of associated reverse signal cancellation circuits. The reverse signal cancellation circuits are coupled to respective pairs of ports of the crosspoint switch and input and output ports of 1:1 current mirrors, in a manner that affords bidirectional buffering between the crosspoint switch and a pair of bidirectional signaling ports that terminate respective signaling links, without signal reflections.

The invention discloses a power supply device for an electromagnetic induction module of an electromagnetic liquid crystal touch screen, belonging to periphery equipment of computers. Without changingthe function of the touch screen, the current requirement of the electromagnetic induction module for the computer is lowered to below 1mA. The working current of the electromagnetic induction moduleis not directly supplied by a USB interface of the computer again but supplied by a power module of the touch screen. A voltage conversion circuit and a switch circuit are connected between the powermodule and the electromagnetic induction module and are respectively connected with the USB interface of the computer. A power end of the USB is connected with a control port and a power input end ofthe switch circuit. An output port of the voltage conversion circuit is connected with an input port and a power input end of the switch circuit. By adopting the device, after the working current ofthe electromagnetic induction module is supplied by the power module of the touch screen, the output current of the USB interface of the computer is greatly lowered, thereby avoiding the aging of a USB controller of the computer.

A stroke magnet arrangement in which the magnetic discontinuity in the pole tube is formed by means of a reduction in the effective material thickness, for example a reduction in the thickness, in particular the wall thickness of the magnetically effective material, of the armature facing the pole iron The end faces of the core segments and the bases arranged on the pole core segments in the interior of the pole tube are each provided with contours which allow mutual axial overlapping. This makes it possible to obtain an advantageous influence of the force-stroke-characteristic curve of the stroke magnet with low manufacturing effort.

The invention discloses an unmanned aerial vehicle control system which comprises a radio frequency management unit, including a receiving module for receiving signals, an enhancement module for collecting signals of the receiving module and a processing module, the processing module receives the signals from the enhancement module and the enhancement module comprises a first coupler and a secondcoupler. The receiving module receives signals of different frequency bands, and the first coupler and the second coupler carry out enhancement processing on the signals. Compared with the prior art,the radio frequency management unit can search two frequency bands at the same time, more signals can be received, the accuracy is improved, and the impedance of the receiving module is adjusted through filtering, signal amplifying, signal integrating and receiving module impedance adjusting, according to the invention, the filter filters out unnecessary clutters, the performance of the receivingmodule can be effectively enhanced, only no more than 20 satellites can be searched under the conventional condition of the existing single-frequency GPS on the market at present, by use of the system, more than 40 satellites can be searched in each frequency band, and the highest centimeter-level precision can be achieved.
